  The java.text.Collator fails to be serialized despite of implementing the
java.io.Serializable interface. Unexpected exception NotSerializableException
for class java.text.EntryPair is thrown during the serialization process.

Here is the test demonstrating the bug:
---------------CollatorTest.java--------------
import java.text.Collator;
import java.io.IOException;
import java.io.ByteArrayOutputStream;
import java.io.ObjectOutputStream;

public class CollatorTest {

  public static void main(String args[]) {

    ObjectOutputStream stream = null;

    try {

      stream = new ObjectOutputStream(
        new ByteArrayOutputStream()
      );

    } catch(IOException e) {
      System.out.println("Unexpected exception : " + e);
      System.exit(1);
    }

    try {

      stream.writeObject(Collator.getInstance());

    } catch(IOException e) {
      System.out.println("Unexpected exception : " + e);
    }

  }

}
-----------The test output------------
#>java CollatorTest
Unexpected exception : java.io.NotSerializableException: java.text.EntryPair
